As I headed down 18th from Castro to Dolores, I filtered by maybe a dozen cars - this is definitely a part of my commute that is much faster on bike than in a car. I noted that I rode right past a cop, and figured that he probably couldn't care less and if Jym Dyer is to be believed, the filtering was legal anyway (though bypassing a garbage truck and the 4 cars stuck behind it by detouring onto the sidewalk was not as holy. To my credit I dismounted and "schluffed" by the one pedestrian I saw.
At the intersection of 18th and Dolores I heard the cop's loudspeaker go off. Cyclist spidey sense goes off and assumes that "The Man" has a beatdown in store for the cyclist, but he was 3 cars back and he wasn't talking to me. I listened to the remainder of his lecture and caught "PUT YOUR HANDS AT TEN AND TWO". I glanced back at the car and watched the flustered driver putting away her cellphone.
Amusing. Though I think he should have said "PULL OVER".
